Mushroom growing on some cow dung!
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.

The cracking on the cap as it dries is telling you that at the microscopic level the surface is made of spherical cells rather than elongate hyphae (which can't pull away from each other in this patchwork fashion). Stropharia has elongate hyphae (and tends to be more yellow). This is probably a dung Panaeolus spp, which has black spores, perhaps P. semiovatus. Agrocybe spp, also grow on dung, and also have this kind of cap structure, but like Stropharia it tends to be more yellow, and both Agrocybe and Stropharia have brown spores.
